what kind of power gains can you expect form this? I have a early '98 SVT?


With a '98 SVT I'd say you can stand to gain a few more ponies over that estimated 5-7. You should also read this post.

1) I know a normal UIM gasket will not work, but I assume the SVT DH UIM gasket will work as its only 13cfm.
2) Since this is guranteed, is EH going to send a certificate back with this part flow benched or whatever so we know were pushing 193cfm?

3) As everyone else has brought up, how we gonna know that 193cfm on a standard UIM is doable.

4) Was the prototype a non-SVT UIM?


1) Get a Felpro gasket (check the 3L FAQ for a p/n). It should work just fine.
2) Don't know.
3) Are you asking if a standard non-honed UIM will allow for this honing process (i.e. enough excess material)?
4) No. SVT UIM. Don't know what year.
